DodgeFan01 Posted June 2, 2009 Share Posted June 2, 2009 Hey guys, I have an 88 comanche with the 2.5 in it and it normally runs like a champ, but every once in a while if it is Very humid out/rain Very hard she won't start, :fs1: it just cranks and cranks like it's not getting a spark or something. :wall: Any ideas what it could be? :dunno: It happened this morning, first time in a while, and it is raining hard right now, but once it is done raining I am going to dig into it and hopefully get it fixed. :hmm: Link to comment Share on other sites More sharing options...
Akula69 Posted June 2, 2009 Share Posted June 2, 2009 Condensation inside the distributor cap. Link to comment Share on other sites More sharing options...
DodgeFan01 Posted June 2, 2009 Author Share Posted June 2, 2009 I thought about that, but I just replaced it a month ago, does that make any difference? Is there any way to seal it up so it doesn't happen? Link to comment Share on other sites More sharing options...
Akula69 Posted June 2, 2009 Share Posted June 2, 2009 Replacing it may not solve the problem...it is not really a factor of "new" or "old" in some cases. You probably would not want to seal the dist cap to the distributor, but you can test my theory by picking up a can of what is commonly called Contact cleaner at the auto parts store. This displaces water and evaporates (it usually contains a lot of ether). Next time the truck does this, pull the dist cap and give it a liberal dose...if it is condensation inside the cap it will be removed and the truck should start right up.

sinkrun Posted June 2, 2009 Share Posted June 2, 2009 My dads old dodge truck would do this and sometimes just quit completely in the rain. It was the electronic pick-up in the distributor. Link to comment Share on other sites More sharing options...
FxRacing282 Posted June 3, 2009 Share Posted June 3, 2009 haha, if there is an arc and any contact cleaner in that cap. i wanna see that. sounds like moisture in the cap. they have a vent don't they? make sure the hose or breather is proper.

I agree, contact cleaner fumes and an arc :eek: I'd use WD40, that's what it was originaly used for, (W)ater (D)isplacement. :smart: Link to comment Share on other sites More sharing options...
DodgeFan01 Posted June 3, 2009 Author Share Posted June 3, 2009 Well it finally stopped raining yesterday, I went out there and she fired right up. I'll check the cap tonight and see if anything looks odd. Link to comment Share on other sites More sharing options...
